I just went to play Hearts against some bots and they are not playing.

After the set up they just sit there and don't exchange cards.

Hello,
this is a temporary bug after the latest reboot.

Until it is solved, kick the bot that hasn't discarded his cards yet, and the new one will do it. Assuming other players are bots too, kick them too to repeat the same process. It should work normally after the discard phase is over.

Edit: it already seems to be fixed in the reboot that just occured.

Hello,

This is now fixed. Thank you for signaling.
